Until now, oxygen concentrators have been very similar – heavy, bulky, noisy, or requiring frequent maintenance. EverFlo from Respironics is a unique stationary concentrator that delivers what homecare providers want and patients deserve. The EverFlo is quiet and lightweight (14.5 kg or about 32 lbs), making it portable and easy to move around the room or be taken in a car, wherever the patient needs their respiratory therapy to take place. If you’re looking for an effective, continuous-flow oxygen therapy, then Philips EverFlo oxygen concentrator is the answer.
